The question que es conjunctivitis comes from Spanish and translates to what is conjunctivitis in English. Conjunctivitis is a very common eye condition that affects people of all ages around the world. It occurs when the conjunctiva, a thin transparent membrane that covers the white part of the eye and the inside of the eyelids, becomes inflamed or irritated. This inflammation leads to symptoms such as redness, discomfort, and discharge, which can range from mild to severe depending on the cause. Understanding what conjunctivitis is, how it develops, and how it can be treated is important for maintaining good eye health and preventing its spread, especially in contagious cases.
What Is Conjunctivitis?
Conjunctivitis is the medical term for inflammation of the conjunctiva. It is also commonly known as pink eye because the affected eye often appears red or pink due to enlarged blood vessels in the conjunctival tissue.
Simple Definition
Conjunctivitis is an eye condition caused by infection, allergies, or irritation that leads to inflammation of the conjunctiva.
Why It Happens
This condition occurs when the eye’s natural protective barrier becomes irritated or infected, triggering an immune response.
Structure of the Conjunctiva
To understand conjunctivitis, it is important to first understand the conjunctiva itself. The conjunctiva plays a key role in protecting and lubricating the eye.
Main Parts
- Bulbar conjunctiva covers the white part of the eye
- Palpebral conjunctiva lines the inside of the eyelids
Functions
- Protects the eye from dust and microorganisms
- Keeps the eye moist with mucus and tears
- Supports immune defense of the eye surface
Types of Conjunctivitis
Conjunctivitis can be classified into several types depending on its cause. Each type has different symptoms and treatment methods.
Viral Conjunctivitis
This is the most common form and is usually caused by viruses such as adenovirus.
- Highly contagious
- Often spreads in schools and workplaces
- Usually starts in one eye and spreads to the other
Bacterial Conjunctivitis
This type is caused by bacterial infections.
- Produces thick yellow or green discharge
- May affect one or both eyes
- Can be treated with antibiotic eye drops
Allergic Conjunctivitis
This occurs when the immune system reacts to allergens.
- Caused by pollen, dust, or pet dander
- Usually affects both eyes
- Not contagious
Irritant Conjunctivitis
This type is caused by exposure to irritants such as smoke or chemicals.
- Usually temporary
- Improves when irritant is removed
Causes of Conjunctivitis
There are several causes of conjunctivitis, and understanding them helps in proper treatment and prevention.
Infectious Causes
- Viruses such as adenovirus
- Bacteria like Staphylococcus or Streptococcus
Non-Infectious Causes
- Allergic reactions
- Environmental irritants
- Contact lens misuse
Symptoms of Conjunctivitis
The symptoms of conjunctivitis can vary depending on the type, but there are several common signs to look out for.

Touching infected eye secretions and then touching another surface or person can spread the infection.
Indirect Contact

- Using contaminated makeup
- Touching shared objects like doorknobs
Airborne Droplets
Some viral infections can spread through coughing or sneezing droplets.
Diagnosis of Conjunctivitis
Doctors can usually diagnose conjunctivitis through a simple eye examination.
Eye Examination
A healthcare provider examines the eye for redness, swelling, and discharge.
Medical History
Questions about symptoms, allergies, and recent exposure help identify the cause.
Laboratory Testing
In rare cases, a sample of eye discharge may be tested to identify bacteria or viruses.
Treatment of Conjunctivitis
Treatment depends on the underlying cause of the condition. Most cases are mild and can be treated effectively.
Viral Conjunctivitis Treatment
- No specific antiviral treatment in most cases
- Artificial tears for comfort
- Cold compresses to reduce swelling
